Description

本発明は注出キャップに関する。 The present invention relates to a dispensing cap.

従来、液体洗剤、液体柔軟剤等の粘性の高い内容液を充填した容器本体の口部に装着される注出キャップとして、注出筒と周壁部の間に液回収空間を設けたものがある。 Conventionally, as a pouring cap attached to the mouth of a container body filled with a highly viscous content liquid such as a liquid detergent or a liquid softening agent, there is one in which a liquid recovery space is provided between a pouring cylinder and a peripheral wall portion. .

この従来の注出キャップを用いて、容器本体の内容液を注出するときには、注出キャップにおける注出筒の外周面を相手容器の開口部の縁部に載せるようにして当接させた状態で、容器本体を傾け、注出筒の注出口から相手容器に内容液を注出する。このとき、相手容器に対する注出筒の当接位置が安定化しないと、内容液をスムースに注出作業することができない。注出筒が相手容器から外れれば、内容液は相手容器の外にこぼれ、周辺を汚すことになる。 When the content liquid of the container body is poured out using this conventional pouring cap, the outer peripheral surface of the pouring cylinder in the pouring cap is brought into contact with the edge of the opening of the counterpart container Then, the container body is tilted, and the content liquid is poured out from the spout of the dispensing cylinder into the counterpart container. At this time, the content liquid cannot be smoothly poured out unless the contact position of the dispensing cylinder with respect to the counterpart container is stabilized. If the dispensing tube comes off from the counterpart container, the liquid content will spill out of the counterpart container and the surrounding area will be soiled.

そこで、特許文献１に記載の注出キャップでは、注出筒における周壁部の上端部よりも上方に位置する外周面であって、該注出筒の上端部より下方に、該注出筒の外周面の液注出方向を臨む前側中央部から径方向の外側に突出するリブ状係合部を形成している。これにより、注出筒の外周面のリブ状係合部を相手容器の開口部の縁部に係止させることにより、相手容器に対する注出筒の当接位置を安定化させようとするものである。 Therefore, in the pouring cap described in Patent Document 1, an outer peripheral surface located above the upper end portion of the peripheral wall portion of the pouring tube, and below the upper end portion of the pouring tube, A rib-like engagement portion is formed that protrudes outward in the radial direction from the front central portion facing the liquid pouring direction on the outer peripheral surface. Thus, the rib-like engagement portion on the outer peripheral surface of the dispensing cylinder is locked to the edge of the opening of the counterpart container so as to stabilize the contact position of the dispensing cylinder with respect to the counterpart container. is there.

特許文献１に記載の注出キャップは、注出筒の外周面の前側中央部にて径方向に突出するリブ状係合部を有するようにしたものであるが、注出筒の外周面のリブ状係合部を相手容器の開口部の縁部に係止させた状態で、容器本体及び注出キャップがそれらの中心軸まわりに僅かでも回動すると、リブ状係合部は相手容器の開口部の縁部に対する係止位置からずれてその係止状態を解除し易く、相手容器に対する注出筒の当接位置を確実に安定化させることに困難がある。 The pouring cap described in Patent Document 1 has a rib-like engagement portion that protrudes in the radial direction at the front center portion of the outer peripheral surface of the pouring tube. When the container body and the pouring cap are slightly rotated around their center axes in a state where the rib-shaped engaging portion is locked to the edge of the opening of the counterpart container, the rib-shaped engaging portion is There is a difficulty in reliably stabilizing the abutting position of the dispensing tube with respect to the counterpart container because it is easy to release the locked state from the locking position with respect to the edge of the opening.

本発明の課題は、注出キャップにおける注出筒の外周面を相手容器の開口部の縁部に載せて安定的に当接でき、安定した姿勢で注出作業できるようにすることにある。 An object of the present invention is to place the outer peripheral surface of the dispensing cylinder in the dispensing cap on the edge of the opening of the counterpart container so as to be able to come into contact stably and to perform the dispensing operation in a stable posture.

請求項１に係る発明は、内容液が収容される容器本体の口部に装着され、注出筒を有する注出キャップであって、注出筒との間に液回収空間を設けて該注出筒を囲み、かつ該注出筒に底壁部を介して結合された周壁部を有し、注出筒における周壁部の上端部よりも上方に位置する外周面であって、該注出筒の上端部より下方に、該注出筒の外周面の周方向に延びる段差部が形成された突出部を有するようにしたものである。 The invention according to claim 1 is a pouring cap that is attached to the mouth portion of the container main body in which the content liquid is accommodated and has a pouring tube, and is provided with a liquid recovery space between the pouring tube and the pouring cap. An outer peripheral surface surrounding the outlet tube and having a peripheral wall portion coupled to the pouring tube via a bottom wall portion, the outer peripheral surface being located above the upper end of the peripheral wall portion of the pouring tube, A projecting portion is formed below the upper end of the tube, and a step is formed extending in the circumferential direction of the outer peripheral surface of the dispensing tube.

本発明によれば、注出キャップにおける注出筒の外周面が有する突出部の周方向に延びた段差部が、相手容器の開口部の縁部に安定的に係止できる。従って、注出筒の外周面を相手容器の開口部の縁部に安定的に当接でき、安定した姿勢で注出作業を行うことができる。 According to this invention, the level | step-difference part extended in the circumferential direction of the protrusion part which the outer peripheral surface of the extraction | pouring pipe | tube in the extraction | pouring cap has can be latched stably to the edge of the opening part of the other party container. Therefore, the outer peripheral surface of the dispensing cylinder can be stably brought into contact with the edge of the opening of the counterpart container, and the dispensing operation can be performed in a stable posture.

An inner peripheral threaded portion 211 provided in the outer cylinder portion 210 of the cap 200 is screwable.

注出キャップ１００は、注出筒１０を底壁部３０から立設している。注出筒１０は、その中心軸が共通軸Ｏと略一致するように配設され、その上端部の内側を注出口１１としている。また、注出筒１０の後側には、その上下方向の全長に渡って径方向に貫くスリット１２が形成されている。底壁部３０は前側から後側に向かって漸次、下り勾配をなすように傾斜している。注出筒１０が底壁部３０に結合している下端部の内側には、底壁部３０の面内に開口した連通口３１Ａが形成されている。底壁部３０における上記連通口３１Ａの後側で、液回収空間２０に臨む面内には、この連通口３１Ａにつながり、かつ注出筒１０に形成したスリット１２の下端部につながる略矩形状の液回収口３１Ｂが開口している。連通口３１Ａ及び液回収口３１Ｂは底壁部３０の面内に開けた開口領域３１を構成する。 The pouring cap 100 has the pouring cylinder 10 erected from the bottom wall portion 30. The dispensing cylinder 10 is disposed so that the central axis thereof substantially coincides with the common axis O, and the inside of the upper end portion is used as the spout 11. In addition, a slit 12 is formed on the rear side of the dispensing tube 10 so as to penetrate in the radial direction over the entire length in the vertical direction. The bottom wall portion 30 is inclined so as to form a downward slope gradually from the front side toward the rear side. A communication port 31 A that opens in the plane of the bottom wall portion 30 is formed on the inner side of the lower end portion where the dispensing cylinder 10 is coupled to the bottom wall portion 30. A substantially rectangular shape connected to the communication port 31A and to the lower end portion of the slit 12 formed in the dispensing tube 10 in the surface facing the liquid recovery space 20 on the rear side of the communication port 31A in the bottom wall portion 30. The liquid recovery port 31B is open. The communication port 31 A and the liquid recovery port 31 B constitute an open region 31 opened in the plane of the bottom wall portion 30.

計量キャップ２００は、ポリプロピレン等の合成樹脂成形体からなり（透明体又は半透明体からなることが好ましい）、図１、図２に示す如く、容器本体１の口部２に設けた注出キャップ１００における周壁部４０の外周ねじ部４３に螺合する内周ねじ部２１１を備えた外筒部２１０と、この外筒部２１０の内側において筒状壁２２１と底壁２２２を備えた有底筒状の内筒部２２０とを有する。内筒部２２０は、外筒部２１０よりも軸方向の上側及び下側に突出している。内筒部２２０の内部が液体計量空間になる。外筒部２１０と内筒部２２０の筒状壁２２１とはそれらの中心軸を同軸配置し、内筒部２２０は筒状壁２２１の軸方向の一端を開口部２２１Ａとし、筒状壁２２１の軸方向の他端に底壁２２２を設けて、この他端を閉塞している。 The measuring cap 200 is made of a synthetic resin molded body such as polypropylene (preferably made of a transparent body or a semi-transparent body), and as shown in FIGS. 1 and 2, a pouring cap provided at the mouth 2 of the container body 1. The outer cylinder part 210 provided with the inner peripheral screw part 211 screwed to the outer peripheral screw part 43 of the peripheral wall part 40 in 100, and the bottomed cylinder provided with the cylindrical wall 221 and the bottom wall 222 inside the outer cylinder part 210 And an inner cylindrical portion 220. The inner cylinder part 220 protrudes from the outer cylinder part 210 to the upper side and the lower side in the axial direction. The inside of the inner cylinder part 220 becomes a liquid measurement space. The outer cylindrical portion 210 and the cylindrical wall 221 of the inner cylindrical portion 220 are arranged coaxially with their central axes, and the inner cylindrical portion 220 has one end in the axial direction of the cylindrical wall 221 as an opening 221A, and the cylindrical wall 221 A bottom wall 222 is provided at the other end in the axial direction, and the other end is closed.

計量キャップ２００は、外筒部２１０の軸方向に沿う底壁２２２寄りの端部と、内筒部２２０の筒状壁２２１の軸方向に沿う中間部との間を閉じる環状壁２２３を有する。 The measuring cap 200 has an annular wall 223 that closes between an end portion of the outer cylinder portion 210 near the bottom wall 222 along the axial direction and an intermediate portion along the axial direction of the cylindrical wall 221 of the inner cylinder portion 220.

計量キャップ２００は、正立させた容器本体１の口部２に嵌合された注出キャップ１００の周壁部４０が備える外周ねじ部４３に対し、内筒部２２０の底壁２２２を上側に配置させた状態で、外筒部２１０が備える内周ねじ部２１１を着脱して使用される。 In the measuring cap 200, the bottom wall 222 of the inner cylindrical portion 220 is disposed on the upper side with respect to the outer peripheral screw portion 43 provided in the peripheral wall portion 40 of the pouring cap 100 fitted to the mouth portion 2 of the upright container body 1. In this state, the inner peripheral thread portion 211 provided in the outer cylinder portion 210 is attached and detached for use.

従って、容器本体１の内容液を注出するときには、計量キャップ２００の外筒部２１０又は内筒部２２０の筒状壁２２１を把持し、この計量キャップ２００を周方向に回して注出キャップ１００から取外すとともに、注出キャップ１００の注出筒１０を露出させる。 Therefore, when the liquid content in the container main body 1 is poured out, the outer cylindrical portion 210 of the measuring cap 200 or the cylindrical wall 221 of the inner cylindrical portion 220 is gripped, and the measuring cap 200 is turned in the circumferential direction to rotate the discharging cap 100. And the extraction cylinder 10 of the extraction cap 100 is exposed.

次いで、計量キャップ２００の中心軸と注出キャップ１００の中心軸とを交差させるように配置するとともに、注出キャップ１００における注出筒１０の外周面に設けた後述する突出部１３が形成する段差部１４を計量キャップ２００の内筒部２２０における開口部２２１Ａの縁部に係止させる。これによって、注出筒１０の突出部１３よりも上方に位置する外周面を計量キャップ２００の開口部２２１Ａの縁部に載せるようにして当接させた状態で、図７に示す如く、容器本体１を傾けて、注出筒１０の注出口１１から計量キャップ２００の内筒部２２０内に内容液を計量しながら注入する。そしてその後、この計量された内容液を計量キャップ２００の内筒部２２０から、例えば洗濯機、洗面器、衣料等に対して全量注ぎ出す。内容液の注ぎ出しが完了したら、容器本体１を起こし、上述と逆の手順で計量キャップ２００を注出キャップ１００に取付ける。 Next, a step formed by a protrusion 13 (described later) provided on the outer peripheral surface of the dispensing cylinder 10 in the dispensing cap 100 is arranged so as to intersect the central axis of the measuring cap 200 and the central axis of the dispensing cap 100. The portion 14 is locked to the edge of the opening 221 A in the inner cylindrical portion 220 of the measuring cap 200. As a result, as shown in FIG. 7, the outer peripheral surface located above the protruding portion 13 of the dispensing tube 10 is in contact with the edge of the opening 221 A of the measuring cap 200. 1 is tilted, and the content liquid is injected into the inner cylinder portion 220 of the measuring cap 200 from the outlet 11 of the extraction cylinder 10 while being measured. After that, all of the measured content liquid is poured out from the inner cylinder portion 220 of the measuring cap 200 to, for example, a washing machine, a washbasin, clothing, and the like. When pouring of the content liquid is completed, the container body 1 is raised, and the measuring cap 200 is attached to the pouring cap 100 in the reverse procedure to that described above.

内容液の注出後に容器本体１を起こすと、注出のときに注出筒１０の内面に付着した液は注出筒１０の内面を垂れ落ちて底壁部３０の面内の連通口３１Ａから容器本体１内に戻り、注出のときに注出筒１０の外周に沿って垂れた液は液回収空間２０を垂れ落ちてその最深部に位置する底壁部３０の面内の液回収口３１Ｂから容器本体１内に戻る。 When the container body 1 is raised after the content liquid is poured out, the liquid adhering to the inner surface of the pouring cylinder 10 drips down on the inner surface of the pouring cylinder 10 at the time of pouring, and the communication port 31A in the surface of the bottom wall portion 30. From the inside of the container body 1, and the liquid dripping along the outer periphery of the dispensing cylinder 10 drips down the liquid collecting space 20 and collects the liquid in the plane of the bottom wall portion 30 located at the deepest portion thereof. It returns into the container main body 1 from the mouth 31B.

注出キャップ１００において、注出筒１０に形成したスリット１２の下端部が底壁部３０に達していれば、底壁部３０の面内に液回収口３１Ｂを開口する必要なく、注出後に液回収空間２に溜る液をスリット１２及び連通口３１Ａから容器本体１へ回収できる。 In the dispensing cap 100, if the lower end of the slit 12 formed in the dispensing cylinder 10 reaches the bottom wall portion 30, it is not necessary to open the liquid recovery port 31 B in the surface of the bottom wall portion 30. The liquid accumulated in the liquid recovery space 2 can be recovered to the container body 1 from the slit 12 and the communication port 31A.

しかるに、注出キャップ１００にあっては、図２乃至図４に示す如く、注出筒１０における周壁部４０（上筒部４１）の上端部よりも上方に位置する外周面であって、該注出筒１０の上端部より下方に、該注出筒１０の外周面の周方向に延びる段差部１４が形成された突出部１３を有する。突出部１３の外周面１４Ａは、段差部１４から注出筒１０の下方に延在し、段差部１４から注出筒１０の上方に延在する外周面１４Ｂよりも前方に膨出され、外周面１４Ａと外周面１４Ｂとの境界部に該段差部１４を形成する。この突出部１３が形成する段差部１４は、容器本体１内の内容液が注出筒１０を通って注出される計量キャップ２００の内筒部２２０における開口部２２１Ａの縁部に安定して係止できる。本実施例では、突出部１３は、注出筒１０の外周面の周方向において、該注出筒１０からの液注出方向を臨む前側中央部に設けられる。但し、突出部１３は、注出筒１０の外周面の全周に渡って設けられても良い。 However, in the pouring cap 100, as shown in FIGS. 2 to 4, the outer peripheral surface of the pouring tube 10 is located above the upper end of the peripheral wall portion 40 (upper tube portion 41). Below the upper end portion of the dispensing cylinder 10, there is a protruding portion 13 formed with a stepped portion 14 extending in the circumferential direction of the outer peripheral surface of the dispensing cylinder 10. 14 A of outer peripheral surfaces of the protrusion part 13 are extended below the pouring cylinder 10 from the level | step-difference part 14, are bulging ahead rather than the outer peripheral surface 14B extended above the pouring cylinder 10 from the level | step-difference part 14, The step 14 is formed at the boundary between the surface 14A and the outer peripheral surface 14B. The step portion 14 formed by the protruding portion 13 is stably engaged with the edge portion of the opening 221A in the inner cylindrical portion 220 of the measuring cap 200 through which the content liquid in the container body 1 is poured out through the dispensing tube 10. You can stop. In the present embodiment, the protruding portion 13 is provided at the front center portion facing the liquid dispensing direction from the dispensing tube 10 in the circumferential direction of the outer peripheral surface of the dispensing tube 10. However, the protrusion 13 may be provided over the entire circumference of the outer peripheral surface of the dispensing tube 10.

従って、容器本体１の内容液を計量キャップ２００へ注出するときに、図７に示す如く、注出筒１０の外周面が有する突出部１３に形成された周方向に延びる段差部１４を計量キャップ２００の開口部２２１Ａの縁部に係止させた状態で、容器本体１及び注出キャップ１００がそれらの中心軸まわりにある程度回動しても、該突出部１３の周方向に延びた段差部１４は計量キャップ２００の開口部２２１Ａの縁部からずれ落ちてその係止状態を解除するに至ることがない。よって、計量キャップ２００に対する注出筒１０の当接位置を確実に安定させることができ、安定した姿勢で注出作業を行うことができる。 Accordingly, when the content liquid in the container body 1 is poured into the measuring cap 200, the stepped portion 14 extending in the circumferential direction formed on the protruding portion 13 of the outer peripheral surface of the dispensing cylinder 10 is weighed as shown in FIG. Even when the container main body 1 and the extraction cap 100 are rotated around their central axes to some extent while being locked to the edge of the opening 221A of the cap 200, the step extending in the circumferential direction of the protruding portion 13 The portion 14 does not slip off from the edge of the opening 221A of the measuring cap 200 to release the locked state. Therefore, the contact position of the dispensing cylinder 10 with respect to the measuring cap 200 can be reliably stabilized, and the dispensing operation can be performed in a stable posture.

注出キャップ１００は、周壁部４０の内周面の少なくとも一部、本実施形態では下筒部４２の内周面４４が、該注出キャップ１００の軸方向になす傾きを略鉛直方向に沿わせる。同時に、注出筒１０に設けられる突出部１３は、段差部１４から該注出筒１０の下方に延びており、該注出筒１０からの液注出方向を臨む前側中央部に突出部１３を膨出させるように形成したことにより、該突出部１３の外周面１４Ａが注出キャップ１００の軸方向になす傾きを、該注出筒１０の内周面１５が注出キャップ１００の軸方向になす傾きと異ならせ、該外周面１４Ａの傾きの方が鉛直方向に近いものとされている。これにより、注出筒１０における突出部１３の外周面１４Ａと、周壁部４０の内周面４４とは、共に略鉛直方向に向いて互いに平行間隔をなすものになる。 In the dispensing cap 100, at least a part of the inner circumferential surface of the peripheral wall portion 40, in this embodiment, the inner circumferential surface 44 of the lower cylinder portion 42 is inclined along the substantially vertical direction in the axial direction of the dispensing cap 100. Make it. At the same time, the protruding portion 13 provided on the dispensing tube 10 extends from the stepped portion 14 to the lower side of the dispensing tube 10, and the protruding portion 13 is formed at the front central portion facing the liquid dispensing direction from the dispensing tube 10. Is formed so that the outer peripheral surface 14A of the projecting portion 13 is inclined in the axial direction of the pouring cap 100, and the inner peripheral surface 15 of the pouring tube 10 is axially directed to the pouring cap 100. The inclination of the outer peripheral surface 14A is closer to the vertical direction. As a result, the outer peripheral surface 14A of the projecting portion 13 and the inner peripheral surface 44 of the peripheral wall portion 40 in the dispensing tube 10 are both substantially parallel to each other in the substantially vertical direction.

従って、計量キャップ２００の内筒部２２０をその開口部２２１Ａの側から注出キャップ１００の周壁部４０と注出筒１０との間の液回収空間２０に挿入し、計量キャップ２００を注出キャップ１００に螺着するとき、計量キャップ２００は注出キャップ１００の周壁部４０の略鉛直方向に沿う内周面１５と、注出筒１０の略鉛直方向に沿う外周面１４Ａとの間の概ね平行をなす間隔内にその内筒部２２０を案内されつつ螺着される。これにより、計量キャップ２００が注出キャップ１００に斜めに螺着されることなく、簡易に正しい螺着状態を得ることができる。 Accordingly, the inner cylindrical portion 220 of the measuring cap 200 is inserted into the liquid recovery space 20 between the peripheral wall portion 40 of the discharging cap 100 and the discharging tube 10 from the opening 221A side, and the measuring cap 200 is inserted into the discharging cap. When screwed to 100, the measuring cap 200 is generally parallel between the inner peripheral surface 15 of the peripheral wall portion 40 of the dispensing cap 100 along the substantially vertical direction and the outer peripheral surface 14A of the dispensing tube 10 along the substantially vertical direction. The inner cylinder portion 220 is screwed while being guided within an interval. Thereby, the correct screwing state can be easily obtained without the measuring cap 200 being screwed obliquely to the dispensing cap 100.

また、注出筒１０における突出部１３よりも上方に位置する外周面１４Ｂは、図３（Ｃ）、図４（Ｂ）に示す如く、注出キャップ１００の軸方向に直交する横断面がＶ字断面状に屈曲している。注出筒１０のＶ字断面のＶ字部が該注出筒１０の周方向で該注出筒１０からの液注出方向を臨む前側中央部に設けられるとき、このＶ字部が注出筒１０の上端部の内側に形成される注出口１１を液注出方向に向く嘴状とする点で、注出口１１による液注出方向の指向性を向上する。 Moreover, the outer peripheral surface 14B located above the protrusion part 13 in the extraction | pouring cylinder 10 has the cross section orthogonal to the axial direction of the extraction | pouring cap 100 as shown in FIG.3 (C) and FIG.4 (B). Bent in a cross-sectional shape. When the V-shaped section of the V-shaped cross section of the dispensing cylinder 10 is provided in the front central portion facing the liquid dispensing direction from the dispensing cylinder 10 in the circumferential direction of the dispensing cylinder 10, this V-shaped section is dispensed The directivity in the liquid dispensing direction by the spout 11 is improved in that the spout 11 formed on the inner side of the upper end of the cylinder 10 is shaped like a bowl facing the liquid dispensing direction.

ところが、容器本体１の内容液を計量キャップ２００で注出するとき、注出筒１０は、該突出部１３よりも上方に位置するＶ字断面のＶ字部の外周面１４Ｂを計量キャップ２００の開口部２２１Ａの縁部に当接してその周方向に転がり易く、該注出筒１０のその当接姿勢を不安定にさせ易い。しかしながら、本発明では、注出筒１０の外周面の突出部１３が周方向に延びた段差部１４を形成し、この突出部１３の段差部１４がその周方向に延びたある程度広い範囲において計量キャップ２００の開口部２２１Ａの縁部に係止するものであることから、計量キャップ２００に対する注出筒１０の当接位置を確実に安定化できる。 However, when the content liquid in the container body 1 is poured out by the measuring cap 200, the dispensing cylinder 10 has an outer peripheral surface 14 B of the V-shaped section positioned above the projecting portion 13. The edge of the opening 221 A comes into contact with the edge of the opening 221 A and easily rolls in the circumferential direction. However, in the present invention, the protruding portion 13 on the outer peripheral surface of the dispensing tube 10 forms a stepped portion 14 extending in the circumferential direction, and the stepped portion 14 of the protruding portion 13 is measured in a somewhat wide range extending in the circumferential direction. Since it is engaged with the edge of the opening 221A of the cap 200, the contact position of the dispensing tube 10 with respect to the measuring cap 200 can be reliably stabilized.

従って、注出筒１０の突出部１３よりも上方のＶ字部の外周面１４Ｂが計量キャップ２００の開口部２２１Ａの縁部に当接して該注出筒１０が転がり易い場合にも、計量キャップ２００に対する注出筒１０の当接姿勢を安定化できる。 Therefore, even when the outer peripheral surface 14B of the V-shaped portion above the protruding portion 13 of the dispensing tube 10 abuts on the edge of the opening 221A of the measuring cap 200, the dispensing cap 10 can easily roll. The abutting posture of the dispensing cylinder 10 with respect to 200 can be stabilized.

また、注出筒１０における突出部１３において段差部１４の近傍に位置する外周面１４Ａは、図３（Ｃ）、図４（Ｂ）に示す如く、該注出筒１０における該突出部１３よりも上方に位置する外周面１４Ｂに比べて、注出キャップ１００の軸方向に直交する横断面における曲率半径Ｒ（図４（Ｂ））が大きいものとされている。 Further, the outer peripheral surface 14A located in the vicinity of the stepped portion 14 in the projecting portion 13 of the dispensing tube 10 is more than the projecting portion 13 of the dispensing tube 10 as shown in FIGS. 3 (C) and 4 (B). In addition, the radius of curvature R (FIG. 4B) in the cross section perpendicular to the axial direction of the dispensing cap 100 is larger than that of the outer peripheral surface 14B positioned above.

これにより、段差部１４の輪郭を形成する突出部１３の外周面１４Ａは、より大きな丸味をもって注出筒１０の外周面の外方に張り出るものになり、結果として該注出筒１０の外周面の周方向のより広い範囲に段差部１４を延在させるものになる。従って、注出筒１０の突出部１３よりも上方の外周面１４Ｂが注出先となる計量キャップ２００の開口部２２１Ａの縁部に載るようにして当接した状態で、容器本体１及び注出キャップ１００がそれらの中心軸まわりにある程度回動しても、該突出部１３の周方向のより広い範囲に延びた段差部１４が計量キャップ２００の開口部２２１Ａの縁部により安定的に係止でき、計量キャップ２００に対する注出筒１０の当接姿勢をより安定化できる。 As a result, the outer peripheral surface 14A of the projecting portion 13 that forms the contour of the stepped portion 14 protrudes outward from the outer peripheral surface of the pouring cylinder 10 with a greater roundness, and as a result, the outer periphery of the pouring cylinder 10 The step 14 is extended over a wider range in the circumferential direction of the surface. Accordingly, the container body 1 and the pouring cap are in a state in which the outer peripheral surface 14B above the projecting portion 13 of the pouring cylinder 10 is in contact with the edge of the opening 221A of the measuring cap 200 serving as the pouring destination. Even if the 100 pivots around the central axis to some extent, the stepped portion 14 extending in a wider range in the circumferential direction of the protruding portion 13 can be stably locked by the edge of the opening 221A of the measuring cap 200. The contact posture of the dispensing tube 10 with respect to the measuring cap 200 can be further stabilized.

尚、注出筒１０に設けられる突出部１３は、段差部１４から注出筒１０の下方において、更に外方に複数回階段状に突出させて、注出筒１０の外周面１４Ａの周方向に延びる複数の段差部を形成しても良い。また、突出部１３は、段差部１４から注出筒１０の下方において、突出させた後、突出量を低減させ、また突出を繰り返す形状に、所謂、ギザギザ又は波状をなすように凹凸を繰り返して、注出筒１０の外周面１４Ａの周方向に延びる複数の段差部を形成しても良い。このように、注出筒１０の段差部１４の下方の外周面１４Ａにおいて、更に複数の段差部を設けることで、使用者が注出筒１０の外周面を相手容器の開口部の縁部に載せる位置を調整可能となる。 Note that the protruding portion 13 provided on the pouring tube 10 protrudes from the step portion 14 below the pouring tube 10 further outward in a stepwise manner, and the circumferential direction of the outer peripheral surface 14A of the pouring tube 10 A plurality of step portions extending in the direction may be formed. In addition, the protruding portion 13 is protruded from the stepped portion 14 below the dispensing cylinder 10, and then the protruding amount is reduced, and the protruding portion 13 is repeatedly uneven so as to form a so-called jagged or wavy shape. A plurality of step portions extending in the circumferential direction of the outer peripheral surface 14A of the dispensing cylinder 10 may be formed. In this manner, by providing a plurality of step portions on the outer peripheral surface 14A below the step portion 14 of the dispensing tube 10, the user can place the outer peripheral surface of the dispensing tube 10 on the edge of the opening of the counterpart container. The mounting position can be adjusted.

注出キャップ１００は、図５に示す如く、注出筒１０の外周面の液注出方向を臨む前側中央部であって、該注出筒１０における上端の注出口１１に沿う外縁（上端側の外周面１４Ｂの最上部）に、該注出口１１から外方に向けてカール状に傾斜する液切り用リップ１１Ｌを形成している。従って、注出筒１０から注出される液の注出筒１０の外面への回り込みを防止できる。 As shown in FIG. 5, the dispensing cap 100 is a front center portion facing the liquid dispensing direction on the outer peripheral surface of the dispensing cylinder 10, and has an outer edge (upper end side) along the dispensing outlet 11 at the upper end of the dispensing cylinder 10. On the outer peripheral surface 14B, a liquid draining lip 11L inclined in a curl shape outward from the spout 11 is formed. Therefore, it is possible to prevent the liquid poured out from the dispensing tube 10 from going around the outer surface of the dispensing tube 10.

また、容器本体１の内容液を計量キャップ２００へ注出している図７に示す如くの注出作業中に、注出筒１０の外周面が有する突出部１３に形成された周方向に延びる段差部１４を計量キャップ２００の開口部２２１Ａの縁部に係止された状態から容器本体１及び注出キャップ１００が使用者の手元寄りに引かれたとき、注出筒１０の上端部の外縁に形成されている液切り用リップ１１Ｌが計量キャップ２００の開口部２２１Ａの縁部の内側面に係止し、注出筒１０が計量キャップ２００の開口部２２１Ａの縁部から脱落しにくいものとする。 Further, during the pouring operation as shown in FIG. 7 in which the liquid content in the container body 1 is poured into the measuring cap 200, a step extending in the circumferential direction formed on the protruding portion 13 of the outer peripheral surface of the pouring cylinder 10 is provided. When the container body 1 and the pouring cap 100 are pulled closer to the user's hand from the state in which the portion 14 is locked to the edge of the opening 221A of the measuring cap 200, the outer edge of the upper end portion of the pouring tube 10 is The liquid draining lip 11L formed is locked to the inner side surface of the edge of the opening 221A of the measuring cap 200, and the dispensing cylinder 10 is difficult to drop off from the edge of the opening 221A of the measuring cap 200. .

The liquid dripping capture part 60 extending in the circumferential direction of the peripheral wall 40 is located at a position through a large gap G0 (the distance G0 between the center line of the first liquid dripping prevention part 71 and the center line of the liquid dripping catching part 60). Provided.

本実施例において、液ダレ捕捉部６０は周壁部４０における上筒部４１の内周面の下端部１カ所に設けられ、上筒部４１の周方向に延在する液捕捉溝６０Ａによって形成される。液捕捉溝６０Ａは、前述の液ダレ防止部７１、７２の液溜り溝７１Ａ、７２Ａよりも大きな溝幅と大きな溝深さを有している。液ダレ捕捉部６０は、上筒部４１の内周面の上下方向の２カ所以上に設けられても良い。 In the present embodiment, the liquid dripping capturing portion 60 is provided at one lower end portion of the inner peripheral surface of the upper cylindrical portion 41 in the peripheral wall portion 40, and is formed by a liquid capturing groove 60 A extending in the circumferential direction of the upper cylindrical portion 41.

従って、注出キャップ１００にあっては、液ダレ捕捉部６０及び液ダレ防止部７０を設けたことによる以下の作用効果も奏する。 Therefore, in the pouring cap 100, the following effects obtained by providing the liquid dripping capturing part 60 and the liquid dripping preventing part 70 are also exhibited.

(a)注出キャップ１００において、周壁部４０の内周面の上下方向に離隔する複数位置のそれぞれに、該周壁部４０の周方向に液溜り溝７１Ａ、７２Ａが延在された液ダレ防止部７０（７１、７２）が設けられる。従って、注出キャップ１００からの液の注出を連続して行ったり、粘度の高い液の場合、液の注出後に容器本体１を起こすことによって液回収空間２０の下端側に垂れ落ちて溜っていた液が、次の注出時に周壁部４０の下端側からその内周面を伝って該周壁部４０の上端側に向かって垂れ出るとき、その液は複数の液ダレ防止部７０（７１、７２）の液溜り溝７１Ａ、７２Ａに順に取り込まれてその流れを制止され、液ダレを防止される。これにより、周壁部４０の上端側への液の流出量を減じ、液が周壁部４０の上端を経てその外周面に回り込み、該外周面に付着することが回避される。 (a) In the pouring cap 100, the liquid dripping prevention in which the liquid pool grooves 71 A and 72 A are extended in the circumferential direction of the peripheral wall portion 40 at each of a plurality of positions separated in the vertical direction of the inner peripheral surface of the peripheral wall portion 40. Part 70 (71, 72) is provided. Therefore, when the liquid is continuously discharged from the discharge cap 100 or the liquid has a high viscosity, the container body 1 is raised after the liquid is discharged to sag to the lower end side of the liquid recovery space 20 and accumulate. When the liquid that has been dripped down from the lower end side of the peripheral wall portion 40 toward the upper end side of the peripheral wall portion 40 from the lower end side of the peripheral wall portion 40 at the time of the next pouring, the liquid is a plurality of liquid dripping prevention portions 70 (71 72) are sequentially taken into the liquid pool grooves 71A and 72A, and the flow thereof is stopped, and dripping is prevented. Thereby, the outflow amount of the liquid to the upper end side of the peripheral wall part 40 is reduced, and it is avoided that the liquid flows around the outer peripheral surface through the upper end of the peripheral wall part 40 and adheres to the outer peripheral surface.

注出キャップ１００からの液の注出時に、第１液ダレ防止部７１の液溜り溝７１Ａを乗り越えた液は、第２液ダレ防止部７２等のより下流側に配置されている液ダレ防止部７２（底壁部３０から遠い上側の液ダレ防止部７２）の液溜り溝７２Ａに取り込まれて液ダレを防止され、周壁部４０の上端にまで達することを確実に回避される。 The liquid that has passed over the liquid pool groove 71A of the first liquid dripping prevention unit 71 when the liquid from the dispensing cap 100 is dispensed is prevented from dripping on the downstream side of the second liquid dripping prevention unit 72 and the like. The liquid is prevented from dripping by being taken into the liquid pool groove 72A of the portion 72 (the upper liquid dripping prevention portion 72 far from the bottom wall portion 30), and reliably reaching the upper end of the peripheral wall portion 40.

このとき、周壁部４０の内周面に設けられる液ダレ防止部７０（７１、７２）の液溜り溝７１Ａ、７２Ａは、該内周面の周方向に延在される凹凸部、凹部、又は凸部等により形成でき、注出キャップ１００の成形時にムリ抜きされる金型により簡易に成形される。従って、簡易な構造により、周壁部４０の外周面に内容液が付着するのを防止できる。 At this time, the liquid pool grooves 71A and 72A of the liquid dripping prevention part 70 (71, 72) provided on the inner peripheral surface of the peripheral wall part 40 are uneven portions, concave portions, or the like extending in the circumferential direction of the inner peripheral surface. It can be formed by a convex portion or the like, and is easily formed by a mold that is removed when the pouring cap 100 is formed. Therefore, it is possible to prevent the content liquid from adhering to the outer peripheral surface of the peripheral wall portion 40 with a simple structure.

(b)底壁部３０に近い下側の第１液ダレ防止部７１における周壁部４０の前側中央位置Ｃから周方向の両側への延在長が、底壁部３０から遠い上側の第２液ダレ防止部７２における周方向の延在長より短い。従って、注出キャップ１００からの液の注出時に各液ダレ防止部７１、７２によって液ダレを防止した後、容器本体１を起こし、各液ダレ防止部７０（７１、７２）の液溜り溝７１Ａ、７２Ａに取り込まれている液を液回収空間２０の下端側に垂れ落として容器本体１に戻そうとするとき、第２液ダレ防止部７２等のより上側の液ダレ防止部７２の液溜り溝７２Ａにおける両側延在端から垂れ落ちる液は第１液ダレ防止部７１等のより下側の液ダレ防止部７１の液溜り溝７１Ａにおける両側延在端の側方を素通りしてそれらのより下側の液ダレ防止部７１に当たって制止されることなく、スムースに垂れ落ちる。 (b) The extension length from the front center position C of the peripheral wall portion 40 to both sides in the circumferential direction in the lower first liquid dripping prevention portion 71 near the bottom wall portion 30 is the second upper portion far from the bottom wall portion 30. It is shorter than the extending length in the circumferential direction in the liquid dripping prevention part 72. Therefore, after the liquid dripping prevention part 71, 72 prevents the liquid dripping at the time of the liquid dispensing from the dispensing cap 100, the container body 1 is raised, and the liquid collecting groove of each liquid dripping prevention part 70 (71, 72). When the liquid taken in 71A, 72A hangs down to the lower end side of the liquid recovery space 20 and returns to the container main body 1, the liquid in the liquid sag prevention part 72 above the second liquid sag prevention part 72 or the like. The liquid dripping from the both ends extending in the pool groove 72A passes through the sides of the both ends extending in the liquid pool groove 71A of the lower liquid dripping prevention section 71 such as the first liquid dripping prevention section 71 and the like. It slid down smoothly without being stopped by hitting the liquid dripping prevention portion 71 on the lower side.

(c)周壁部４０の内周面で各液ダレ防止部７０（７１、７２）よりも底壁部３０に近い位置であって、かつ最下位置にある第１液ダレ防止部７１に対し、各液ダレ防止部７１、７２が互いに離隔されている間隔Ｇ1よりも大きな間隔Ｇ0を介する位置に、該周壁部４０の周方向に液捕捉溝６０Ａが延在された液ダレ捕捉部６０が設けられる。また、この液ダレ捕捉部６０の液捕捉溝６０Ａは周壁部４０の中央位置Ｃから、該中央位置Ｃの両側に延在され、その延在長が各液ダレ防止部７０（７１、７２）における液溜り溝７１Ａ、７２Ａの延在長より長く設定される。 (c) With respect to the first liquid dripping prevention part 71 which is closer to the bottom wall part 30 than the respective liquid dripping prevention parts 70 (71, 72) on the inner peripheral surface of the peripheral wall part 40 and located at the lowest position A liquid dripping trap 60 in which a liquid trapping groove 60A extends in the circumferential direction of the peripheral wall 40 at a position through a gap G0 larger than the gap G1 at which the liquid dripping prevention parts 71 and 72 are separated from each other. Provided. Further, the liquid catching groove 60A of the liquid dripping catching part 60 extends from the central position C of the peripheral wall part 40 to both sides of the central position C, and the extension length thereof is each liquid dripping preventing part 70 (71, 72). Is set longer than the extension length of the liquid reservoir grooves 71A and 72A.

従って、前述したと同様に、液回収空間２０の下端側に溜っていた液が、次の注出時に周壁部４０の下端側からその内周面を伝って該周壁部４０の上端側に向かって垂れ出るとき、その液の流れが複数の液ダレ防止部７１、７２に到達する前段階で、液ダレ捕捉部６０の液捕捉溝６０Ａがその液の一部を受け止めてその液ダレを捕捉する。これにより、この液ダレ捕捉部６０を越えて下流側に流出し、その下流側に位置する各液ダレ防止部７１、７２の液溜り溝７１Ａ、７２Ａにより取り込まれるべき液量を低減するものになり、各液ダレ防止部７１、７２による液ダレ防止作用の確実を図ることができる。 Accordingly, as described above, the liquid that has accumulated in the lower end side of the liquid recovery space 20 travels from the lower end side of the peripheral wall portion 40 to the inner peripheral surface thereof toward the upper end side of the peripheral wall portion 40 at the next pouring. When the liquid drips, the liquid capture groove 60A of the liquid sag capturing unit 60 receives a part of the liquid and captures the liquid sag before the flow of the liquid reaches the plurality of liquid sag prevention units 71 and 72. To do. As a result, the amount of liquid that flows out downstream from the liquid dripping capturing part 60 and should be taken in by the liquid collecting grooves 71A and 72A of the liquid dripping preventing parts 71 and 72 located on the downstream side is reduced. Thus, the liquid sag prevention action by the liquid sag prevention portions 71 and 72 can be ensured.

液ダレ捕捉部６０における周壁部４０の前側中央位置Ｃから周方向に沿う両側への延在長が、例えば周方向の全周に渡り、各液ダレ防止部７１、７２の延在長より長い。従って、液ダレ捕捉部６０による液ダレ捕捉範囲を周壁部４０の周方向に沿う長い範囲に及ぼし、該液ダレ捕捉部６０よりも下流側に流出する液量を確実に低減できる。 The extending length from the front center position C of the peripheral wall 40 in the liquid dripping capturing part 60 to both sides along the circumferential direction is longer than the extending length of the liquid dripping preventing parts 71 and 72, for example, over the entire circumference in the circumferential direction. . Therefore, the liquid dripping capture range by the liquid dripping capturing section 60 is exerted on a long range along the circumferential direction of the peripheral wall section 40, and the amount of liquid flowing out downstream from the liquid dripping capturing section 60 can be reliably reduced.

液ダレ捕捉部６０と第１液ダレ防止部７１との間隔Ｇ0が、各液ダレ防止部７１、７２の間の間隔Ｇ1よりも大きいから、前述した次の注出時に液回収空間２０の下端側に溜っていた液が液ダレ捕捉部６０を乗り越えて第１液ダレ防止部７１に到達するまでの距離（液到達時間）が大きくなる。従って、液ダレ捕捉部６０を乗り越えてから周壁部４０の内周面に沿って第１液ダレ防止部７１の側に向かう液の流れを、該周壁部４０の内周面の周方向の前側中央位置Ｃに集めることができる。これにより、各液ダレ防止部７０（７１、７２）が周壁部４０の前側中央位置Ｃから周方向に沿う両側への一定範囲だけに延在されているときにも、液ダレ捕捉部６０を乗り越えた液を各液ダレ防止部７１、７２による液ダレ防止範囲に向けてより多量に集め、その液を各液ダレ防止部７１、７２の液溜り溝７１Ａ、７２Ａによって確実に制止することができ、各液ダレ防止部７１、７２による液ダレ防止効果の確実を図ることができる。 Since the gap G0 between the liquid dripping capture part 60 and the first liquid dripping prevention part 71 is larger than the gap G1 between the liquid dripping prevention parts 71 and 72, the lower end of the liquid recovery space 20 at the time of the next dispensing described above. The distance (liquid arrival time) until the liquid accumulated on the side reaches the first liquid dripping prevention part 71 after getting over the liquid dripping capturing part 60 is increased. Accordingly, the flow of the liquid that travels over the liquid dripping capturing portion 60 and then toward the first liquid dripping prevention portion 71 along the inner peripheral surface of the peripheral wall portion 40 is caused to flow forward in the circumferential direction of the inner peripheral surface of the peripheral wall portion 40. It can be collected at the central position C. Thereby, even when each liquid dripping prevention part 70 (71, 72) is extended only to the fixed range to the both sides along the circumferential direction from the front side center position C of the surrounding wall part 40, the liquid dripping capture | acquisition part 60 is made. It is possible to collect a larger amount of the liquid that has passed over toward the liquid dripping prevention range by the liquid dripping prevention portions 71 and 72 and reliably stop the liquid by the liquid collecting grooves 71A and 72A of the liquid dripping prevention portions 71 and 72. In addition, the liquid dripping prevention effect by the liquid dripping prevention portions 71 and 72 can be ensured.

更に、注出キャップ１００にあっては、前述した如く、注出筒１０の注出口１１及び注出筒１０の周囲の液回収空間２０が、底壁部３０の面内に開けた開口領域３１（連通口３１Ａ及び液回収口３１Ｂ）を介して容器本体１の内部に連通している。このとき、本実施形態では、開口領域３１が、該開口領域３１を含む底壁部３０の全面積の４割以上を占めるものとされている。 Further, in the pouring cap 100, as described above, the opening region 31 in which the pouring port 11 of the pouring tube 10 and the liquid recovery space 20 around the pouring tube 10 are opened in the plane of the bottom wall portion 30 are provided. It communicates with the inside of the container main body 1 via (communication port 31A and liquid recovery port 31B). At this time, in this embodiment, the opening area 31 occupies 40% or more of the total area of the bottom wall portion 30 including the opening area 31.

従って、詰替えの際、詰替え容器から供給される液を効率的に容器本体１の内部に収容することができる。また、液注出後に注出筒１０及び液回収空間２０に残った液をそのように大きな開口領域３１を通して容器本体１へ効率的に回収できる。これにより、液注出後に液回収空間２０に溜る液の残量を低減し、次の注出時に液回収空間２０の下端側から周壁部４０の内周面を伝って該周壁部４０の上端へ向かって垂れ出る液の流出量を低減できる。 Therefore, at the time of refilling, the liquid supplied from the refilling container can be efficiently accommodated inside the container body 1. In addition, the liquid remaining in the dispensing cylinder 10 and the liquid collection space 20 after the liquid is dispensed can be efficiently collected into the container body 1 through the large opening region 31. Thereby, the remaining amount of the liquid collected in the liquid recovery space 20 after the liquid is dispensed is reduced, and the upper end of the peripheral wall 40 is transmitted from the lower end side of the liquid recovery space 20 to the inner peripheral surface of the peripheral wall 40 at the next extraction. It is possible to reduce the outflow amount of the liquid dripping toward the head.

本発明によれば、注出キャップにおける注出筒の外周面を相手容器の開口部の縁部に載せて安定的に当接でき、安定した姿勢で注出作業を行うことができる。 According to the present invention, the outer peripheral surface of the dispensing cylinder in the dispensing cap can be placed on the edge of the opening of the counterpart container and stably contacted, and the dispensing operation can be performed in a stable posture.
